79k stars is a good signal that “tool-calling” is becoming a real developer workflow, but it also feels like the ecosystem is about to hit the same wall browser extensions and npm did: discovery + permissions + trust. The next 10x improvement probably isn’t “more servers”, it’s better capability scoping (least-privilege), reproducible installs/locking, clear UX for what tools can read/write, and some kind of reputation/audit trail so teams can adopt MCP servers without turning their agent into a supply-chain hazard.
